single-character message, my zip code, my callsign, and all I get back
is:<br>

I tried zip code 90210 and it worked.<br>

process of working on a program which provides a US Weather forecast </div><div>via
APRS message. I have most of the kinks worked out and it is ready for
testing</div><div>by a larger group.</div><div><br></div><div>Send a
single character APRS message to KI6WJP and the program will respond
with a </div><div>brief forecast for your location.</div><div><br></div><div>You
can specify "where" and "when" you want the forecast. If you wish a
full forecast</div><div>add the word "full" to your "where" and "when".
The full forecast is spread across</div><div>multiple APRS message.
The default "brief" forecast usually fits within a single</div><div>message.</div><div><br></div><div>"where"
is any APRS callsign/object, zipcode, grid, or decimal lat/lon as long
as it is </div><div>located in a place covered by the US National
Weather Service.</div><div><br></div><div>"when" is any day of the week
with optional night. I.e. Wednesday night</div><div><br></div><div>The
forecast is derived from the US National Weather Service point forecast.</div><div>Usually
the forecast is produced within 1 or 2 seconds, but during periods of</div><div>heavy
activity, the weather service can take 20 or 30 seconds.</div><div><br></div><div>The
latitude/longitude for the requested object is extracted from <a
moz-do-not-send="true" href="http://api.aprs.fi">api.aprs.fi</a>, </div><div>As
a result, anything that appears on <a moz-do-not-send="true"
href="http://aprs.fi">aprs.fi</a> is valid including </div><div>CWOP
stations and AIS ships.</div><div><br></div><div>Here are some example
forecast requests that can be sent to KI6WJP:</div><div><br></div><div>Any
message less than 3 characters</div><div> Returns a brief forecast
for the current location of the sending station.</div><div>Tomorrow
96067</div><div> Returns tomorrow's forecast for Mount Shasta, CA</div><div>Tonight</div><div>
Returns the forecast for tonight at your current location</div><div>Tuesday
night full</div><div> Returns the Tuesday night full forecast at
your current location.</div><div>w1aw</div><div> Returns the current
forecast for the location of station W1AW</div><div>usna-1 Sunday</div><div>
Returns the forecast for the Army Navy football game on Sunday. </div><div>
(Assuming usna-1 is at the stadium)</div><div>CN81uh</div><div>
Returns the forecast for the center of maidenhead grid CN81uh</div><div>36.5786/-118.2920</div><div>
Returns the forecast for the summit of Mount Whitney.</div><div><br></div><div>Currently
the program is running on a raspberry Pi on a home dsl internet
connection.</div><div>The program is single threaded and can handle a
single forecast request at a time.</div><div>Things are still in
development and may break at any time. </div><div><br></div><div>Obviously
for this to work via RF, a transmit capable i-gate is necessary.</div><div><br></div><div>Many
